A glass as well as calomel electrode system was found to develop a potential of -0.0412V when dipped into a pH 6.00 buffer. While in an unknown solution the cell potential was found to be -0.2004 V. Compute the pH and the activity of hydrogen ion in the unknown solution.
When a 8.26-g sample of gaseous hydrogen bromide dissolves in 36.2 g of water in a coffee-cup calorimeter (see above figure) the temperature rises from 25.00 oC to 71.53 oC. Calculate H in kJ/mol HBr for the solution process.
A reaction mixture initially contains 0.86 M NO and 0.86 M S03. Determine the equiibrium pressure of NO2 if Kc for the reaction at this temperature is 0.0118.
Transition from the n=7 to n=2 level of the hydrogen atom yields a photon at the edge of human visual perception. Determine the energy and wavelength of this light.
Calculate the specific heat capacity of a sample liquid if this 100 g sample of an unknown liquid absorbs 2000 J of heat energy, raising the liquid's temperature from 50 degree Celsius to 70 degree Celsius?
What volume of a 0.236 M HCHO2 must be added to 1.00 L of a 0.500 M solution of NaCHO2 to give a pH of 3. Assume that volumes are additive.
How many peaks would you expect to find in the NMR spectrum of caffeine? What characteristic absorption bands would you expect to find in the infrared spectrum of caffeine?
What is the percent ionization at equilibrium in a 0.60 M solution of dimethylamine, (CH3)2NH (Kb = 5.1 × 10-4), at 25oC
Ammonia is a gas whose smell we detect in manure as well as in some cleaning solutions, among other things. If the concentration of this noxious gas can be controlled by regulating the pH of the water because only the non-protonated form is volati..
What is the volume of a gas at T=35.0C and P=675 torr if the same sample occupied 42.6L at T=-27.3C and P=1.000 atm.

If a column is exchanged for a similar column that is half the length of the first column, how would that change the retention time of a solute
What will the temperature be when the ice cube has just melted. Use 4.184 J/K*g for the specific heat capacity of ice and water. If the water is then heated to 80 degrees C by burning methane (delta H= =890.31 kJ/mol) how many grams of methane wou..
